Bob's Plumbing charges $50 for a house call

Mathematics
1 answer:
viva [34]3 years ago
8 0

Answer:

C(8) = $290

Step-by-step explanation:

Since Bob's Plumbing charge a flat fee of $50, then it is the y-intercept.

As detailed in the given problem, x is the number of hours they work.  

They charge $30 for every x number of hours on the job. This represents the slope.

C(x) represents the total cost of working for x number of hours.

Given these factors, we can establish the following function rule:

C(x) = 30x + 50

To evaluate the function for 8 hours of work:

C(8) = 30(8) + 50

C(8) = 240 + 50

C(8) = 290

Therefore, the cost of working for 8 hours is $290.
